Draw Ishihara-transformations (circles In Circle Without Intersection)?
Apr 28, 2011
Question: I need to draw pictures as below in C#/VB.NET Draw ishihara-transformations (circles in circle without intersection)?
Note that my problem is NOT drawing circles in C#.
My problems is drawing them without much whitespace and without intersection.
My thought would be using "Orbits" and then draw the circles with center on the "orbit" lines. (with some orbit lines for bigger and some only for smaller circles)
Private Sub PictureBox1_Paint(ByVal sender As System.Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles PictureBox1.Paint e.Graphics.DrawEllipse(Pens.AliceBlue, New Rectangle(New Point(0, 0), New Size(PictureBox1.Width, PictureBox1.Height))) End Sub
I am trying to draw a circle in VB.Net, .Net version 4.Nothing shows up in the paintbox.
Using Visual Basic 9 I want to draw a circle and gradientFill the circle using FillGradientStyle = Centraland a FillStyle = SolidWith the same results as can be achieved in The Power Packs 3.0 OvalShape.
I searched this forum for the answer before posting this and from what i have noticed there is no "simple" way ofcourse "simple" definition varies from one person to another
my definition of simple is something like this Line(x1,y1,x2,y2,color) or something like that.[code]...
User launches the application, enters width of circle, then enters width and height of rectangle and presses the button. Then app draws the circle with rectangle inside of it (if it fits). App should output the coordinates x1;y1 , x1;y2 , x2;y1 , x2;y2 (corners of rectangle) somewhere on form and would be great if it could post those coordinates on x and y axes (optional).
how to draw the circle at the below position, i have marked where i should get the angle. And i m also sending my piece of code.
Plz tell how to draw the circle at 180 degree on x-axis, For green circle. And later i should draw at the same place semi circle, dnt know how to draw them... i.e on green circle at zero n 180 degrees.
I am having some trouble drawing a circle that is constant when the program runs. right now I am able to create one of my clock hands (that is going counterclockwise), but I can't figure out how to draw the circle of the clock, any suggestions? [Code]
I need to write some code which draws a predefined circular path (say 48pix diameter) and use a timer to delay it to show it being drawn. I need to use GDI+ to do this. My guess is on the Timer.Tick, I would set some Point value for the next point on the path, and then call Invalidate to raise the Paint event.
To print a point(.) on the given position from the formulas above.
Now heres my question how do I get Visual Basic too calculate:
x= (10 x CosA)+40 y=(10 x SinA) +20
360 times i.e 0rad-2Pirad and then pass the x & y [(x,y)] point to my cursor position code so that a '.' is printed at that position. I.e I will end up with a circle made out of 360 '.'
I would asume that a loop is used and also an array to store the 360 Pi values. I'm finding it extremely hard to even get Vb to calculate the Cos of an angle.
is it possible to draw an accurate circle in vb.net with mouseDown and mouseUp boundaries? I only manage to create circle-settings with rectangular boundaries using DrawEllipse. I've tried to work around it using pythagoras but it just doesn't work and I'm pretty sure I've got my maths right...
Is it possible to define a circle with DrawEllipse(pencil,x1,y1,width,length) ?
I have developed a program which continuously draws a circle using a timer. Now every time the circle gets displays it flickers and which is because i have used me.refresh. Is there any other way to avoid this flickering.
Here is my code Private Sub Timer1_Tick(ByVal sender As Object, ByVal e As EventArgs) Handles Timer1.Tick
is there a control which allows me t amke slideshows of some kind?Like one image flowing into an other after a period of time (like the desktop backgrounds of Windows 7).
I am using VS2010, and I understand that when I publish a web application, the Web.config I am using is transformed based on the build settings.i.e. When I choose Debug, it uses my development SQL server, and when I choose Release, it uses my production SQL server.What I want to know is: Can I, using only the built in Visual Studio Development Server, select "Release" from the Configuration drop-down, and then the green "Continue" arrow (F5), and run using the transformed Web.config settings?
In VB2005 GDI+, it's not too difficult to get zooming and panning working together, or rotating and panning. But I am finding it very difficult to get all three functions working in coordinatioin. The code below is the nearest I have reached so far. It's a working example on a standard Windows Form, but please supply your own image. The user can drag the image with the left mouse button, and toggle wheel zooming or rotating by tapping the space bar. Both zooming and rotating work. But the stationary centre of zooming or rotating (marked by a red cross in the example) remains relative to the image.
(VB 2008) ok im making space invaders for a midterm project, that is i made space invaders and then lost my thumb drive, WITHOUT BACKING UP ANY OF MY PROJECTS. point is its due tomorrow and im having trouble with one of my methods. i have a collection that stores all the missles the enemy shoots, then i have a collection that stores each picture box that makes up the barriers. my method is supposed to search thro both collections and check to see if they intersect. if they are both visible they become invisible creating an illusion that they dissappear. i hav organized the rest of my code to ignore the missles and barriers if they are invisible but this part isnt working for some reason.
This is my problem...I have created graphicspaths (gp) in Visual Basic...but every gp has a name. So I want to print every name next to the gp. I use GetBounds to get the nearest rectangle around the gp. But like for a circle the name will be quite far away from the gp. Now I want to draw a line from the name to the outline of the gp...can somebody help me with this little part of script?
I have made considerable progress on a game I am making, but one of the fundamentals of it relies on collision detection. At the moment, I am using Rectangle.IntersectsWith() to check "collision" between two PictureBoxes, but I don't want everything all square (graphics, etc). So I set about adjusting regions and have ended up with a circular button (from the MSDN example). What I'd like to know is this: Is there any way I can check intersection between any two OBJECTS, not just rectangles? As in, if the rectangle intersects with or is inside the circle in any way then how do I check it programmatically?
I have a list of user names (we'll call 'original list') one object is returning. I have a list of user names (we'll call 'filtration list') another object is returning. I am testing a method that returns all of the items from the original list not in the filtration list. Ideally what I want is something like:
However my m8 will support me with any problems about the server, but he doesn't know how to fix this one in the client.The Sub have to create random sized circles, which are showed when u just hit some **** in space.It works fine in VB6, but in .NET i got a lot of ISSUES:
Sub DrawHitCircles(ByRef accuracy As Short) Dim GO As Single Dim check As Short Dim guns As Short
I am trying to solve this problem since many days. The problem seems to be rather mathematical, but I faced difficulties dealing with Grids and how to store them using visual basic.

In my problem, I have a world of 200 x 200 units divided into 4 x 4 grids (Each of 50 units).
There is a line crosses some areas has the coordinates of Point A (Starting Point) of (XA = 12.43, BA = 159.48) and Point B coordinates (Ending Point) of (XB = 112.95, YB = 20.95).
The question is, how can find the length of (A to C1), (C1 to C2), (C2 to C3), (C3 to C4), (C4 to C5) and finally (C5 to B)?
In addition, how can I indicate the square in which the line is inside?
note that the method should work for all conditions (-ve and +ve line slopes) and for different A and coordinates.
I am working on a program to generate 50 circles starting with the smallest in the center of the form. The circles do not over lap and the appear to grow outward. Each circle has to be a random color. I have the code that generates what I need but all the circles are the same color. I was thinking about either using an array to hold each circle and color as to not assign the same color to all of them but not sure about putting a graphic in an array. I also think maybe a nested loop of some sort but was unable to figure one out.
Private Sub mainForm_click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Click Dim penColor As New Pen(Color.FromArgb(Rnd() * 255, Rnd() * 255, Rnd() * 255, Rnd() * 255), 2)
[Code]......
This works to do what I need to get done, I just need each circle to have a random color as it is drawn.
The purpose of this (maybe there is a better method I don't know) is to so the user can say what order they want pieces of code to be compiled in. Sort of like a flow-chart. I want it somewhat animated, so, example being 3D circles the user drags and drops in the order they want things.
1. I need 4 circles inside of a form.
2. I need it so when the user selects the circle, they can drag and drop it in an order.
3. User clicks OK to finish their chosen order.
I haven't designed anything before that needed to check the borders of the form etc.
I've got a fun little question for you all. I am designing a program that allows you to click on a picture to input data in certain areas. What I want to do it pretty allow someone to take a look at a picture. Click the add point tool, then select an area on the picture where it places a circle. I then want them to be able to go back to the circle and modify data if necessary
